When make up the drawbacks of video can not check near surface, and the abnormal position that can be found to vortex regard in time
Frequency supplement checks.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is:
Eddy current probe is pried through in one kind, which includes endoscope module 1, electric and pneumatic module, coil module, metal
Solenoid, alignment positioning device are vortexed cable, endoscope module cable and composite cable;
Endoscope module is located at front end, and electric and pneumatic module, electric and pneumatic module is arranged in endoscope module rear end
It is connect with coil module by metal spiral pipe, coil module front and back end is separately connected alignment positioning device, is vortexed cable and line
Module connection is enclosed, coil module is hollow structure, and endoscope module cable is connect across coil module with endoscope module, electronic
Or the service cable or tracheae of pneumatic module are connect across coil module with electric and pneumatic module, are vortexed cable, endoscope mould
Group cable and electric and pneumatic module service cable are exported by composite cable.
The endoscope module, electric and pneumatic module, coil module, metal spiral pipe outside diameter are less than heat transfer bore;
When endoscope module stretches into heat-transfer pipe to be measured, middle positioning device is contacted with heat transfer inside pipe wall, and the middle positioning device makes to stretch
The endoscope module entered in heat-transfer pipe is in heat-transfer pipe shaft core position.
The endoscope module carries LED light lighting module, and LED light lighting module has dimming function.
The electric and pneumatic module includes motor and electric transmission axis;Endoscope module is mounted on electric transmission axis,
Motor rotates and reverse that endoscope module is driven to extend and retract in safeguard protection shell.
The electric and pneumatic module includes tracheae, piston, spring and pneumatic transmission shaft;Endoscope module is mounted on pneumatic
On transmission shaft, by tracheae aerating, piston pushes pneumatic gearing axis that endoscope module is ejected containment, and spring is utilized after relaxing one's efforts
Elastic force will endoscope module withdraw containment in.
The present invention's has the technical effect that:
(1) eddy current probe is pried through in present invention one kind, electric and pneumatic module makes endoscope module have Telescopic, when
When endoscope module does not work in retraction containment, needs to stretch out when work, increase the safety of endoscope module.
(2) eddy current probe, the electric Drive Mode of electric and pneumatic module, endoscope module peace are pried through in present invention one kind
On electric transmission axis, motor rotates and reverse that endoscope module is driven to extend and retract in safeguard protection shell, makes interior peep
Mirror module telescopic process is steady, and stability is high.
(2) eddy current probe, the pneumatic actuation pattern of electric and pneumatic module, endoscope module peace are pried through in present invention one kind
On pneumatic gearing axis, by tracheae aerating, piston pushes pneumatic gearing axis that endoscope module is ejected containment, after relaxing one's efforts
Endoscope module is withdrawn in containment using the elastic force of spring;The pattern allows axial space to shorten, effectively in endoscope
Module passes through bend loss.
Description of the drawings
Fig. 1 is to pry through eddy current probe schematic diagram in present invention one kind;
In figure:1- endoscope modules, the electric and pneumatic modules of 2-, 3- coils module, 4- metal spiral pipes, 5- centerings positioning
Device, 6- are vortexed cable, 7- endoscope module cables, 8- composite cables.
Specific implementation mode
It is described in detail With reference to embodiment with attached drawing to prying through eddy current probe in one kind of the invention.
As shown in Figure 1, prying through eddy current probe, including endoscope module 1, electric and pneumatic module 2, line in present invention one kind
Module 3, metal spiral pipe 4 are enclosed, alignment positioning device 5 is vortexed cable 6, endoscope module cable 7 and composite cable 8;
Endoscope module 1 is located at front end, and electric and pneumatic module 2, electric and pneumatic mould is arranged in 1 rear end of endoscope module
